Maja and Johan are living at different places, so they are probably not married.

derstädes = ibidem

I don't think there is a word "hemdop". At least not according to SAOB, SAOL or NE. I think they would have said "döpt hemma" (christened at home) if that was the case. The mother wasn't allowed in the church I think, until she was "kyrktagen". I suppose the godmother (or one of the witnesses) carried the child to church.
